A specialized end mill designed to machine high hardened materials up to HRc70 with precision and efficiency. It features a long neck design, which is particularly beneficial when working with workpieces that have a draft angle. The length of the tool's effective neck accommodates the longer interference length required for different draft angles, ensuring optimal performance and avoiding interference issues. The end mill is capable of dry cutting and high-speed cutting thanks to its newly developed raw-material and advanced coating. These enhancements contribute to better heat resistance, wear resistance, and overall tool performance. The ZSLNS20 is engineered to provide excellent workpiece finishes, allowing for high-quality surface results. Whether you're working with challenging materials or aiming for a superior finish, this end mill is a reliable choice for your machining needs.
